A lot of people report the same feeling and the same lights.
There must be something to it.
Since I have a STRONG belief in God (mine is a cosmic God which even the bible references), I see things others don’t and experience things that others can’t always accept.
Some people can’t accept anything unless they can actually reach out and touch it.
I am not sure what you mean by a "cosmic God". I, myself, believe that God is primarily way above and separate from His creation (the cosmos), but chose to interact with us, and even become one of us, because He loves us. His ways, though, are way beyond our understanding. It is enough that we know Jesus, and grow in understanding of Him, primarily through reading The Bible, prayer and by experiencing His loving interaction in our lives. We know that He is just and sin must be punished, but He made a way for us to be saved. We are saved by accepting His Son Jesus who died in our place on the cross, thereby paying the sin debt we owed. God is all about love, loving Him, and loving each other. Love and life are beautiful! Praise The LORD!!!
John 3:16 For God so loved the world (cosmos), that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
